We have already been able to apply our know-how to more than 200 bells in Europe. In addition to a mere condition assessment of the ringing conditions with respect to the ringing loads and the sound quality of bells, damage to bells and clappers was examined and repair concepts worked out. In vibration-dynamically loaded towers, adjusted ringing conditions were determined and the preservation of the building fabric was verified by measurement.

To improve the sound development or to reduce the noise emission of ringing bells, bobbin forms are used, which, in conjunction with individually adapted ringing concepts, enable a targeted sound excitation of bells.

Bells made of replacement materials

In times of material shortage or to reduce costs, bells were made of substitute materials, especially between the end of the 19th century and the middle of the 20th century. The best known replacement materials are

  • Euphon and Brilon special bronze (copper based)
  • Iron hard casting and cast steel (iron based)

To analyze the durability and durability of bells made of these substitute materials, the following peals of bells have been investigated and some of them have already been redeveloped to preserve and improve sound quality:

  • Auferstehungskirche Karlsruhe-Rüppurr: 4 cast steel bells (Bochumer Verein of 1921)
  • St. Georg in Ellingen: 4 cast steel bells (Bochumer Verein from 1922)
  • St. Nikolaus Hofstetten: 3 Euphonglocken (Erdinger bell foundry 1950)

Clapper optimization

To extend the life and to improve the sound development of ringing bells, more than 100 clappers have been individually calculated and designed for bells.

Also for special ringing situations clappers were specially adapted:

  • with pre-damaged bells with welds
  • in the case of vibrationally loaded church towers
  • to reduce the volume
